Reply to Double Akai LPD8 Trouble

I own 2 LPD8's and every time I start traktor I have to go into preferences and tell traktor that LPD #2 is on Y Port both in and out. Now I know that it has something to do with which port it is plugged into on my USB hub. If I move them around then I have to tell it that LPD #1 is on X port. I know this isn't the best way to explain it but has anyone else experienced similar things with traktor and you gear? If so have you found a way to make it stop. I have another USB hub in the mail but they take a while to get here. Any thoughts would be great thanks.
